v IMPROVEMENT IN GRAIN-IBINDERS.

Specification forming part of Letters Patent N 0. 44,513, dated October 4, 1864.

To all whom it may concern Be it known that I, W. W. BURSON, of the city of Rockford, in the county of Winnebago and gtate of Illinois, have invented a new and usefal Grain-Binder; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, forming part of this specification, in the several figures of which similar characters of reference denote the same parts.

Figure 1 is a side elevation, the upright B being removed to show the tying devices. Fig. 2 is a plan view, the tying device being removed. Fig. 3 shows spool-spring s. Fig. 4 is a view of the stationary part m of the cutting and holding device.

My invention has reference to the binding of grain upon the reaper-platform with twine, cord, or string and consists of certain combination of devices hereinafter to be set forth. In the drawing, Fig. l, the vibrating-lever A is hinged at J to its support, which is secured to the uprights R R. The shaft K is supported in its bearings M and L, which latter covers the groove 5 made in said shaft K, in which hook 0 moves, being raised and depressed by the arm 0 moving in cam-groove N, which surrounds shaft K. The fork I) is hinged to shaft K at b, androtates with said shaft, being properly guided by groove 3,0011- structed in the bed-piece of the binder, under shaft K, and eccentric to the axis of said shaft, and of sufficient depth and width to admit said fork and the twine, as hereinafter described, Fig. 2.

The swinging lever d vibrates on its suport d on shaft K, and is moved by arm 0, guided incam-groove O. The lever f, suportiug foot i on bearing f, has on its rear end the weight g and arm h, rising perpendicularly, is moved forward by contact with arm c and backward by weight g. The spool G has wound upon it the twineor band material Win such manner that it shall unwin from the under side. The shaft k, pivoted at r and a, has near its upper end the curved arms 0 0 0 o, and on the lower end the cutters lili 1, and turns one-fourth revolution for each {revolution of shaft K, by which rotation the sheaf portion of the twine is cut from the spool portion, and the end of the latter retained for the next band In operation, this binder is placed upon the latform of anyreaping-machine in such position that the grain can most readily be brought to it in proper order for binding. W en the crank E is over the indicator E, and the lever A fully down under the tying device, all parts are said to be in position of rest.

The twine W is passed from the spool 0,

through the loops X. X and eyelet Y of curved lever A, the end drawn through and held in the hand while the lever is brought down to itsplaceof rest under the tying device, when the hinge H of handle 1) D, being below the range of hinges H and 1, looks lever A when down, and prevents it from rising by the ressure'ofthe gavel upon t.

By the above-described movement the twine W is brought between the point a of shaft K and fork b, and is over the elevations P, D, and U, and the end being still held, the crank E is turned to the right one revolution, whic should fasten the twine .in the holding device Z m. Drawing upward on'handle D, lever A is raised, drawing the requisite length of twine from spool O; the gavel being brought within reach of lever'A, the handlel) is pushed down, bringing the two ends of the band together within the tying device. \Vhile lever A i: being moved down, the ratchet-rod F is car ried over the ratchet-pulley of spool 0, turn ing back the spool and drawing upon th twine, insuring the band to be drawn tightl around the gavel, when the crank E is turne to the right, rotating shaft K, when fork takes in the twine at recess Q, of lever A, ca rying the twine into groove 3. At the san time stud 1) passes within the curved arm and, by the continued revolution of shaft] turns the cutters l, releasing the end of t' twine, and carrying the continued thread in the cutters, the sheaf portion'is severed frr the spool portion, the end of the latter bei held by the on tters Inn, ,when stud 12 has pass beyond the reach of arni o. The contini rotation of shaft K bringsthe end of. ar against arm h of lever f, moving it forwe the foot t presses the twine into recess V, abling fork b to pass over it in forming loop, when the weight g brings the levet its position of rest. The fork I), follou groove. 3, is brought under shaft K, carrying the ends of the band within reach of the hook c, which is raised by arm a moving in camgroove N, and draws the ends of band through the loop thus formed into the groove 5, when lever d, guided by cam-groove O, is thrown forward, whereby the knot formed around the point of rest. Tnstead of .the hook c moving in groove 5 for the purpose described, suitablyconstructed pinchers, closed 'bya spring or cam-groove, could be used, the object arrived 1 at being to hold'the ends securely and draw them through the loop to form a perfect knot. V

to the side of the sheaf, thereby holding the band tightly around it.

In tying the knot, as just described, the foland the opencharacter ot'the knot, would be lowing points are to-be noted First, the fork very objectionable, to remedy which defects lever 11 is arranged to form a part of the rim,v

holding the .loop until the ends are drawn of lever A, forming an acute angle, which form allows twine of different sizes to be drawn in tightly, and entering groove 3, is held firmly by the form of fork I), just described, and the severed ends of the twine pressing against the outer wall of said groove. To accommodate great unevenness of sizes in twine, the outer wall of said groove may be constructed of some elastic 'material, or held forward by properly-constructed springs, giving greater space for the twine to pass through. Instead of the fork and groove, just described, for holding the ends of the band, the fork could be ar-. ranged to close uponthe'twine by means of a spring, or, if hinged, could be closed by a stud moving in a cam-groove. By either of the the upper surface, roughened ridge or elevation m in the middle, and notch or square offset on the lower surface. The rotary cutters are in the corrugated holders securely retains it. To prevent the severed ends being carried through the cutter m, the ridge m is notched or roughened, thereby preventing the endfrom being carried through.

The end of lever A is c'onstructedwith the eyelet Y, elevation P, recess Q, elevation S, recess T, bridge U, and recess V, which construction brin gs the twine within reach of the tying device and permits the proper movements of the same.

Raising the lever A moves the .ratchet-rod F over the ratchet-pulley ofQspool 0; the weighted end of spool-spring t, aided by the friction of the spring 8, Fig. 3, brings the end of the spring between the nothes of ratchetrod F and the spool-pulleyratchet, thereby severed from the spool portionin the beginning of the tying process, whilefthc loop is forming, enabling the ends to be drawn through said loop to form a perfect knot. Second, the curvature of groovei3 is nearly a section of a spiral curve, and should be at recess Q, the proper distance from shaft K, to insure sulficient length of twine to form the loop, and no more. This groove should approach the axis of shaft K just enou h 0 save any strain give back, thereby loosening the band bere .the knot is tied. Third, when the severed ads are brought to hook 0,.said hook draws em from fork b into groove 5 by arm 0 movg in cam-groove N. 'The construction of vok 0 is very similar to that of fork b, in this, at it forms an acute angle, allowin twine of y size to be drawn tightly in, an the sevzd ends are pressed against the side of said rod and ratchet-pulley to come together, whereby the spool is turned back, drawing the band tightly around the gavel. The amount of ten sion thus brought upon the band can be regulated by a weight or spring acting upon ratchet-rod F and ratchet-pulley.

' What I claim as my'iuvention, and desire to secure by Letters Patent, is-

Hinging-forkb to shaft K, in such man ner that the fork and shaft shall be on oppoi site sides of the twine, in position of rest, whereby a loop is formed in the twine by their rotation, as described. 1
